Combining The Power Of R And D3.js
The amount of unstructured data might account for more than 70%-80% of all data in organisations. Because everyone wants to find hidden treasures in these mountains of information, new tools for processing, analyzing and visualizing data are being developed continually. This post focuses on data processing with R and visualization with the D3 JavaScript library...

Using Custom Tiles In An RStudio Leaflet Map
I posted to Twitter an interactive map using the classic John Snow Cholera dataset and tiles made from Snow’s map, which attracted a fair share of interest...I was inspired to try this by Lincoln Mullen’s tweet that custom historical tiles could be used in an RStudio Leaflet map...Below, I’ll explain how I got this done...

binvis.io - A Browser-based Tool For Visualising Binary Data
I've written a number of posts on this blog on the topic of binary data visualisation. I looked at using space-filling curves to understand the structure of binary data, I've showed how entropy visualisation lets you trivially pick out compressed and encrypted sections, and I've drawn pretty pictures of malware...l recently started toying with the idea of using web technologies to build an interactive visualizer of this sort. One thing led to another... and today, I'm happy to announce a first draft of the idea: binvis.io...

Folding Fractions
Can you fold a piece of paper in half? Of course you can, it’s easy, you just match the two corners along one side. But can you fold it in thirds? You might be able to fold it into thirds with a bit of fiddling and guessing, but what about into fifths? Or sevenths? Or thirteenths? Here is a simple way you can fold a piece of paper into any fraction you would like – exactly – no guessing or fiddling needed! (with tons of visualizations...)...

Maps: Turning Numbers Into People
We knew early that we wanted to have maps all over Socratic...So, we love maps. Now how do we make them?...We explored Google Maps, and Leaflet + Mapbox, but neither fulfilled all our requirements, so one morning, inspired, we built our own solution...We’d had a hunch that D3.js would be the right tool for this job....

d3panels - D3-based Graphics Panels
This is a set of D3-based graphics panels, following Mike Bostock’s Towards Reuseable Charts. They were developed the basis for visualizations in the R/qtlcharts package. The intent is for these panel functions to be usable by others, for other purposes, along the lines of d3.Chart or C3.js. They are developed in CoffeeScript; the source is on GitHub...

pewpew - IPew Attack Map
IPew is a feature-rich, customizable D3 / javascript visualization, needing nothing more than a web server capable of serving static content and a sense of humor to operate...IPew provides a simple framework - based on Datamaps - for displaying cartographic attack data in a (mostly) responsive way and shows how to use dynamic data via javascript event timers and data queues (in case you're here to learn vs have fun - or both!)...
